Altimind UHF Series

JFH2881

JFH2881 is a high performance UHF RFID fixed reader. It is designed upon fully self-intellectual property. Based on proprietory efficient digital signal processing algorithm, it supports fast tag read/write operation with high identification rate. It can be widely applied in many RFID application systems such as logistics, access control, anti-counterfeit and industrial production process control system.


    • Self-intellectual property;
    • 840~960MHz frequency band (frequency customization optional);
    • Based on R2000 design, excellent multi-tag anti-collision operation, fully support EPC CLASS1 G2 \ ISO18000-6B protocol tags;
    • FHSS or Fix Frequency transmission, support RSSI;
    • RF output power up to 30dbm(adjustable);
    • 4 TNC antenna ports support antenna auto-tuning and antenna testing;
    • Support auto-running, answer, trigger and real-time-inventory work mode;
    • Tag buffer size up to 800PCS (Max. 496bits EPC length);
    • Support EPC and TID inventory;
    • Low power dissipation with single +9 DC power supply, POE (Power over Ethernet) is optional;
    • Provide DLL, Demonstration Software source code to facilitate further development;
    • High reliability design, meet the requirements of harsh working environment.
